N2 - The rotationally resolved spectrum of the (000-000) B̃ 2A″-X̃ 2A′ band system [T 000-000=15 859.4638(15) cm-1] of a supersonic molecular beam sample of calcium monohydrosulfide, CaSH, was recorded in the presence of a variable static electric field. The magnitude of the a-principal axis component of the permanent electric dipole moment, |μa|, was determined to be 5.36(4) and 3.78(7) D for the X̃ 2A′ and B̃ 2A″ states, respectively. An analysis of the field free spectra produced values for the (000) B̃ 2A″ vibronic state fine structure parameters of (in cm-1); A′ = 10.433 56(16), B′ = 0.143 43(15), C′ = 0.141 14(15), ∈aa = -5.779 3(19), ∈bb = 0.107 67(88), and ∈cc = 0.032 70(83). An interpretation of the parameters is presented.
